Cooking Steps

Make the mash
1

• See ‘Top Steak Tips!’ (below). Take out the butter 
(for the sauce) from the fridge (to bring to room 
temperature!).
• Boil the kettle. Half-fill a large saucepan with boiling 
water, then add a generous pinch of salt. 
• Peel potato and cut into large chunks. Cook in the 
boiling water over high heat until easily pierced with 
a fork, 12-15 minutes. Drain and return to the pan. 
• Add the butter (for the mash) and milk to potato 
and season generously with salt. Mash until smooth. 
Cover to keep warm.  
TIP: Save time and get more fibre by leaving the potato 
unpeeled.

Get prepped
2

• While the potatoes are boiling, finely chop parsley 
and garlic.
• Trim green beans.
• Trim baby broccoli halving any thicker stalks 
lengthways. 
• Zest lemon to get a pinch, then slice into wedges.
• Pick and finely chop rosemary (see ingredients). 
TIP: Run your fingers down the rosemary stalk to 
remove the leaves easily.

Make parsley butter
3

• In a large frying pan, heat a drizzle of olive oil over 
medium-high heat. 
• Cook garlic until fragrant, 1 minute.
• Transfer to a bowl, add parsley (reserve some for 
garnish!), lemon zest, the softened butter (for the 
sauce) and cracked black pepper. Season with salt 
and mash with a fork to combine. Set aside.

Cook the Porterhouse steak
4

• Return frying pan to medium-high heat with a 
drizzle of olive oil.
• When the oil is hot, cook porterhouse steak for  
3-5 minutes each side for medium-rare, or until 
cooked to your liking. Using tongs, hold steak 
upright and sear fat until golden, 1 minute.
• Remove steak from pan, cover and rest for  
5 minutes. Season with salt. 

Cook the veggies
5

• While the steak is resting, wipe out the frying pan 
and return to medium-high heat with a drizzle of 
olive oil.
• Cook baby broccoli and green beans, tossing, until 
tender, 5-6 minutes. 
• Add rosemary and a squeeze of lemon juice. 
Season to taste with salt and pepper. 

Finish & serve
6

• Thinly slice steak.
• Divide prime porterhouse steak, sautéed greens and 
mash between plates. Season steak with a pinch of 
sea salt flakes, then spoon over parsley butter and 
any resting juices.
• Sprinkle over reserved parsley and serve with any 
remaining lemon wedges. Enjoy! 
Little cooks: Help season and spoon over the butter!
